Homosexuality Turned On and Off in Fruit Flies | LiveScience
Other genes are known to alter sexual orientation, but most just control whether the brain develops as genetically male or female. It's not known why a male brain does male things and a female brain acts in female ways, Featherstone and his colleagues say.
"Based on our previous work, we reasoned that GB mutants might show homosexual behavior because their glutamatergic synapses were altered in some way," Featherstone said. "Homosexual courtship might be sort of an 'overreaction' to sexual stimuli."
To test this, the researchers genetically altered synapse strength, independent of GB. They also gave flies drugs to alter synapse strength. As predicted, they were able to turn fly homosexuality on and off, within hours.
"It was amazing. I never thought we'd be able to do that sort of thing, because sexual orientation is supposed to be hard-wired," Featherstone said. "This fundamentally changes how we think about this behavior."
If you received a pill/pills, would you take it?
